Thin films of $Pb(Zr_xTi_{1-x})O_3$)PZT) were grown on $Pt/SiO_2/Si(100)$ at various temperatures by RF magnetron sputtering method. Surface morphology of these films were studied by using Atomic Force Microscopy(AFM). These films were also analyzed by using Atomic Force Microscopy(AFM). These films were also analyzed by using X-ray photoemission spectroscopy(XPS) for determining their chemical composition and their depth profile. It was found that the films grown at the substrated temperature of $300^{circ}C$ have much more smooth surface characteristics in comparison to those films grown at room temperature, which may be explained in terms of surface mobility of ad-atoms such as Pb. It was also found that Pb enrichment in the near surface region enhanced for the films grown at higher substate temperature.
